Staples 1 1/2" 3-Ring Better Binder, Purple (19061)

Ample Storage
With the Staples Better view binder, 1.5-inch D-rings hold up to 400 sheets of standard 8.5 x 11-inch paper. The rings open with the touch of one finger, so adding or removing sheets is easy.

Sturdy Construction
The integrity of the Staples 400-sheets D-ring binder is largely due to the rubber edges and spine that give it flexibility. When the binder experiences heavy pressure, instead of the cover creasing and becoming crushed, it flexes. Not only does this protect the documents, but it prevents ring misalignment.
